Unformatted text preview: homogeneous reaction in the drop is nA k B where n is an integer (1 or 2) The intrinsic rate expression is given by r k Cn , A with k k0 Exp EA RT (i) Show that the rate constant can be expressed as k T k TR Exp T TR T , where A R TR (ii) Under steady state conditions the diffusive flux of species A in the drop is balanced by the rate of production of species A, which in spherical coordinates is given by A r2 r CA A 0, 0 r R r2 r where A is the molar rate of production of species A per unit volume, and A is the diffusion coefficient for species A. For a non-isothermal...
